i think their parents will approve of their relationship just they dont have the whole house to themselves now so they cant practice child making and not much flirty but looking at dad and mom they sound cool and openminded couple who are in love so im sure they will understand their love
I feel like they will most likely agree to their relationship as they have known Sei for a long time as he is a child hood friend type and is generally a gentleman. Whey do they look like they're in collage??
